This depends on how much data you usally transfer at a time, the
kernel used and the machine under it.
LMBench will show you the differences per system on any system
where it compiles. Just google for it (Author is Larry McVoy).
The decision you have to make is, whether a copy will take longer
than the synchronisation overhead. Don't forget the sleep/wakeup
overhead.
